VALUATION OF PROVISIONS RELATED TO NUCLEAR GENERATION IN FRANCE – BACK-END OF THE NUCLEAR CYCLE, PLANT DECOMMISSIONING AND LAST CORES – AND DEDICATED ASSETS Notes 1.3.2.1, 1.3.16.2.2, 1.3.21.1, 29 and 47 to the consolidated financial statements

Key Audit Matter

Responses

As at December 31, 2017, the provisions recorded to cover obligations relating to nuclear power plants for which EDF is the operator in France total €37,633 million, including €20,326 million with respect to the back-end of the nuclear cycle (management of spent fuel and radioactive waste) and €17,307 million with respect to the decommissioning of nuclear power plants and last cores. The valuation of these provisions is described in Notes 1.3.2.2, 1.3.21.1 and 29.1. It requires defining technical and financial assumptions and using complex calculation models and falls within the scope of the regulatory context described in Note 29.1. They are updated and the assumptions taken into consideration in the models are reviewed at least once a year. These assumptions reflect management’s best estimate at the reporting date of the impacts of the applicable regulation, the implementation of decommissioning and storage processes or changes in the main financial parameters. Furthermore, the Company is required to allocate so-called “dedicated” assets to secure financing of certain categories of nuclear provisions in France. The realisable value of these assets should allow the Company’s commitments relating to the decommissioning of nuclear power plants and long-term storage of radioactive waste in France to be covered (Notes 1.3.16.2.2. and 47). The realisable value of these dedicated assets, for an amount of €28,115 million (or a net carrying amount of €26,502 million) as of December 31, 2017, was determined based on the fair value of diversified equity and bonds investments, and the fair value or the equity value of non-listed assets managed by EDF Invest.

We have analysed the measures for recognising provisions related to nuclear generation in France and gained an understanding of the industrial scenarios for decommissioning nuclear power plants and the solutions adopted in terms of management of spent fuel and radioactive waste. We have assessed the compliance of the provisions with regard to applicable accounting, legal and regulatory measures. We have verified the calculation models used by the Company and assessed the sensitivity of the valuations to the assumptions adopted in terms of cost, forecast cash outflows and financial parameters (discount and inflation rates). Our work also consisted in verifying the type of costs used to determine provisions, assessing the consistency of industrial scenarios adopted by the Company and verifying the reconciliation of forecast costs and forecast cash outflows with these scenarios as well as the available studies and quotes. We have also assessed the reasonableness of: margins for uncertainties and risks included in the provisions, to take into ■ account the degree of control over decommissioning techniques and the management of spent fuel and radioactive waste. the series and mutualisation effects adopted in the quotes for decommissioning ■ nuclear power plants in operation, for which the nominal cost represents €20,563 million to economic conditions at the end of the period, for a provision of €11,616 million in discounted value (Notes 29.1.3 and 29.1.5.2).
